You can use Riemann sums. If you can express your shape using a set of points (x_i,y_i), you can express the area as: area = area + y_i * (x(i+1)-x(i-1))

There is no such formula. To determine the area of an irregular plane shape split it into known shapes such as rectangles, triangles, segments of a circle etc. Determine the area(s) of each of these and sum the results to find the total area.
You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.

the formula depends on the shape of the object
